<h2>Move it!</h2>

<p>To move the car, you'll need to have a name to call it by so you
can change it.  In programming, you name something by using a
<em>variable</em>.  For example, this code creates a variable named
&quot;racecar&quot; to refer to the car:</p>

<pre>
function start() {
  racecar = new Car;
}
</pre>

<p>The <code>racecar</code> part creates a new variable named
&quot;racecar&quot;.  The <code>=</code> sign tells the computer that
when you use &quot;racecar&quot; you are referring to the <code>new
Car</code> object in the game.</p>

<p>Once you have a variable, you can use it to find out about or
change some basic things about the car, like where it's placed.  Try
adding this to your program:</p>

<pre>
function everyFrame() {
  racecar.accelerate();
  racecar.turnRight();
}
</pre>

<p>Now press the Go! button. The new code you added should make your
car drive around in circles!</p>
